Title
(EN) THERMOCHROMIC INDICATOR, PRODUCING METHOD AND CABLE ACCESSORY
(FR) INDICATEUR THERMOCHROMIQUE, PROCÉDÉ DE PRODUCTION ET ACCESSOIRE DE CÂBLE
Abstract
(EN)
Embodiments of the present disclosure provide a thermochromic indicator for a cable accessory. The thermochromic indicator comprises at least one thermochromic layer comprising a liquid crystal material adapted to become colorless transparent in response to a temperature of the cable accessory exceeding a threshold temperature. In this way, the stability of temperature measurement using thermochromic materials is improved and thus its life extends.
(FR)
Des modes de réalisation de la présente invention concernent un indicateur thermochromique pour un accessoire de câble. L'indicateur thermochromique comprend au moins une couche thermochromique comprenant un matériau à cristaux liquides conçu pour devenir transparent incolore en réponse au dépassement d'une température seuil par une température de l'accessoire de câble. Ainsi, la stabilité de la mesure de température à l'aide de matériaux thermochromiques est améliorée et ainsi sa durée de vie est prolongée.
